i believe investing in ICO that requires KYC is reasonable,because this is for investors safety
But if youre referring in bounty hunters that the project requires KYC is unreasonable,because this may use to abuse participants
But you still have to take into account the fact that there are a lot of scammers in the Eco companies market and in the current situation fraudsters can use the registration requirements circle in order to give their project more importance and prospects. That's when many users of cryptocurrency, including participants of the Bounty company and investors, must be alerted, because I do not know where their personal passport data goes.
